Abstract

New business opportunities of digital video such as IP-based inspection require for preserving the data during long term. Digital watermarks remain in the content and provide supplementary evidence of integrity. For them to become practical, a means is needed for processing them in real time on PCs. We previously proposed system architecture and a method to shorten watermarking time by reusing the estimated watermark imperceptibility among neighboring frames. They enable real time processing in a series of captured analog video signals: watermarking the video, encoding it into MPEG4 (QGVA, 1Mbps, 30fps), and storing the video for 12 hours in maximum. We have now evaluated the validity of the system as a software application.
